Because I'm old and crusty, I have only recently started using Reddit. I quickly discovered most of the generic subreddits suck as I've discovered other smaller ones. So I figured, why not share some of the more niche subreddits that you frequent for entertainment.
I'll start. Reverse Animal Rescue: https://www.reddit.com/r/reverseanimalrescue/
Basically, animal rescue footage played in reverse leading to awesome thread titles like "Sicko forces jar onto Fox's head and forces it to retreat"
